väävliline

Väävliline, also known as sulfuric acid, is a strong mineral acid with the chemical formula H2SO4. It is a colorless, odorless, and viscous liquid that is highly corrosive and can cause severe burns. Sulfuric acid is widely used in various industries, including chemical manufacturing, fertilizer production, and oil refining. It is also a key component in the production of other chemicals, such as fertilizers, detergents, and pharmaceuticals.

The term "väävliline" is derived from the Latin word "sulfur," which refers to the element sulfur. Sulfuric acid is produced through the contact process, which involves the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) and the subsequent absorption of SO3 in water to form H2SO4. The contact process is a continuous process that operates at high temperatures and pressures.

Sulfuric acid has a wide range of applications due to its strong acidic properties and its ability to react with a variety of substances. It is used in the production of fertilizers, such as ammonium sulfate and superphosphate, which are essential for agriculture. It is also used in the production of detergents, such as sodium lauryl sulfate, which are used in cleaning products. Additionally, sulfuric acid is used in the production of pharmaceuticals, such as aspirin and penicillin.

However, the use of sulfuric acid also poses significant environmental and health risks. It is a highly corrosive substance that can cause severe burns and damage to the skin, eyes, and respiratory system. It is also a potent acid that can cause environmental damage if released into water bodies, leading to acidification and harm to aquatic life. Therefore, the handling and disposal of sulfuric acid require strict safety measures and regulations to minimize its environmental and health impacts.
